PUZZLE-JOINT.

SPECIFICATION forming part of Letters Patent No. 442,653, dated December 16, 1890.

Application filed September 17, 1890. Serial No. 365,300- (No model.)

T at whom, it may concern.-

Be it known that I, HERMANN WEIssE, a subject of the Emperor of Germany, residing at Carlsluhe, Baden, German Empire, have invented an Improved Inseparable or Puzzle Joint, of which the following is a specification.

My inventionrelates to an inseparable or puzzle joint which unites two bodies or objects in such a manner that a knife-blade or other flat instrument of the kind may be readily passedthrough the joint without separating the two bodies or parts, the same remaining jointed as before.

In the accompanying drawings, Figure 1 is a front elevation of two bodies jointed according to my invention, with a knife-blade cutting through the joint. Fig. 2 is a vertical section of two bodies jointed according to my invention. Fig. 3 is a vertical section of the same, taken at right angles to Fig. 2. Fig. 4. is a bottom view of the upper part or body. Fig. 5 is a top view of the lower part or body. Fig. 6 and 7 are respectively a front and side elevation of a modification of the star-wheel. Figs. 8, 9, 10 and 11 are respectively corresponding views of two other modifications of the star-wheel.

The lower part or body A has a recess 0 around the shaft 13 of sufficient width to allow the star-wheel D, mounted on said shaft B, to turn freely within said recess. The said starwheel carries three or more wings, the outer edges of which are bent to both sides to engage a groove E within a metal piece G, provided in the upper part or body F, to which the lower part A is being jointed by the said star-wheel and groove. The joint effected by the said wheel and groove is so constructed that in passing a knife-blade M or any other fiat blade or similar object between the joint the said blade may pass without severing the upper part F from the lower part A. The

' joint, on the contrary, remains as active as before, though the knife passes through from one side to the other, or vice versa. This rejoint.

ment with the groove E comes free of the same; but before the said wing is disengaged from the groove the next wing to follow enters into engagement with the groove E. By this means no interruption of the joint will occur. The passage for the blade M being cleared to allow the said blade to cut through,

The same must be arranged in width in such a manner that after the blade has passed one wing remains in the center part of the upper body F.

The groove E, instead of being provided within a separate metal piece, as shown in Fig. 4, may as well be out directly into the material of the upper body F.

My invention is destined to be principally applied to toys. In Fig. 1, for instance, the upper and lower body, jointed according to my invention, have the shape of a head and trunk of a person, the head being cut off by the knife M withoutbeing severed, though the knife cuts through as often as maybe desired.

Vhat I claim is- The combination of body A with shaft B and star-wheel D, having laterally-extending edges, and with body F, having a groove adaptedto be engaged by said edges, substantially as specified.

In testimony whereof I hereunto sign my name, in the presence of two subscribing witnesses, this 29th day of August, 1890.

HERMANN WEISSE.
